Specification of Letters Patent.

P.i...ented Nov. 1919075 Application filed March 16. 1905. Serial No. 250.468.

To all whom it may concern:

Be it known that I, ADoLrnE CLMENT, a citizen of the Republic of France, residing in Levallois-Perret, Seine, France, have invented certain new and useful Improve-- ments in Transmission-Gear fer Motor-Lorries and otherV-ehicles, of which the following is a specification.

The transmlssion. gear which forms the subject of this invention and which is more particularly adapted for motor lorries and versal joints` S and S tofthe bevel pinions Q.

and R and consequently to the differential casing M. The two shaftsP P of the differential gear terminate in pinions p p which mesh with internally toothed crowns- E E fixed to the rear wheels D D which are y capable of rotating upon the axle C.

The two stays II Il. of the frame for coupling the' rear axle are passed and rigidly fixed at one extremity upon the axle at :1: and fr respectively, while at their other ex'- tremity they are boltedn together so as to form a V. These stays therefore constitute with the rear axle a rigid triangular frame Which is connected to the chassis or framework of the vehicle A by means of a universal joint and a swivel I rotating in the support J. `This frame transmits the tractive effort from the driving Wheels D D to the framework A of the lorry or the like.

The differential' M carrying the brake drum N is mounted in a gear case K Whichis fixed upon therear axle C; it is driven by the change speed -gear B by the intermediary of the bevel Wheels Q and R and the shaft T which is connected by universal joints S S.

The differential shafts P and I which carry the-driving pinions p p are supported on theone hand by the ball bearings L L mounted in the stays lH H While their other extremities terminate in bosses which fit into the pinions O O of the differential rotating in the inner bearings of the casing M.

Assuming that fiexion of the rear 'axle C takes place, the ball bearings L and L heilig fixed to the stays H H will follow the deformations, as will also the differential shafts which terminate in rounded squares""or bosses permitting of slight Obliquity in the pinions O O. The springs F F are fixed to collars G' vGr provided with shoes and mounted upon two cylindrical bearing faces 0f the rear axle, and are therefore able t0,

, rock freely around this latter.

This system as a Whole forms a bogie supporting the entire mechanism which is connected to the framework in front by a double articulation and at the rear by suspension springs.

The shaft T which is driven from the speed change gear B transmits its movevthe differential gear by a u iversal joint S and connected to the mai shaft by a universal joint S, and a pair of stays H I-I connectedy to said axle near its ends and converging tothe center of the vehicle and connected by a universal joint I J to the frame `ofthe vehicle.

In Witness whereof, I have hereunto signed my name 1n the presence oftwo subscribing Witnesses.
